f Be it known that REN Manoir. citizen `tof the Republic of France, andresident of 53 Rue de Chateaudin, Paris, in the said gepublic, engineer,have invented new and Seful Improvements in Apparatus for lire paring aMixture of Air and Sulfur Dioxid,

"'f'hxch the following is e specification.

expanding device according to the present invention. Fig. 4 is a.'lopgitudinal elevation and Fig. 5 a top view of an apparatus forproducing and distributing the mixture of air and sulfur dioxid providedwith said en` 4pending deslice. v A

. The expanding device consists in a box a oshetfmetal having a part bin which `are arranged series othurizontal tubes fr whose diameterincreases from the lower part upward and are `asselniiled by means ofbent tubes c (these tubes being fixed by means ofremovable bushings) inorder to provide a number of coils of gradualhYr inY creasing cross'section equal to that at the bottles containing the liquid sulfur dioxidfor feeding the apparatus'f.. The lower end of each coil is connected tethe lin a tubular de bottle of sulfur dioxid a. while its upper i 3 aplan of an respective y iextreioity is connected to a free space (ltubular expanding device above described liquid sultur dioxid; u steaminlet aperture which 'is formed in the upper part of the bou a. and doesnot communicate with the room fi in which the coils are arranged.

The steam designed for heating purposes admitted in said space b'throughan up- Aper inlet pipe c and owing to its Contact With the coils thesulfur dioxid absorbs heat therefrom and when it reaches the space d isentirely raporized and expanded. As a preventive means hi'iwever, incase some smali liquidl drops should remain in the mixture, there is.rovided a Wall f against which the sulfur ioxid impinges and whichconstitutes a baffling device over which the sulfur dioxid is made ltopass in order to escape through the outlet g; the upper part of the wallf is provided with a sloping portion fdesigned to ive reater security4against the passage ofiqui In the top of the space d is provided an airinlet h so that it is a mixture et air and expanded sulfur dioxid whichescapes through the outlet g. On one side of space d is provided anopening z' normally closed by a sliding door through which the action ofthe apparatus can be viewed.

As will be seen in Figs.- 4 and 5, the

is connected with the bottles n, a oontaining the liquid sulfur dioxid,these bottles being preferably placed upon a Weighing apparatus o inorder to permit the operator to observe at ,all times the quantity ofsulfur dioxid still remaining; the `gaseous mixture of air and sulfurdioxid as it escapes from space a flows in a known'lnanner in a pipe jwhich contains electrodes k con. nected with a dynamo Z in order toprodtlee electric sparks in the body of the gaseous mixture. The dynamoZ is actuated ""by ine-ans of a driving 'belt through the shaft ot aiii'an m which inits turn is actuated in the saine manner by the primemover.

l chillin- A device for expanding sulfur dioxid and thoroughly mixingthe latter with air, coniprising: a box; series of tubes in said box,the diameter of which increases from bottoni to top; bent tubesconnecting said tubes together in each vertical row; a'connection pieceon the lowest. tube in each vertical rau. for connecting it to a bottlecontaining in the wall of said box; a chamber at the upper part of saidboi: connected with each.

vertical row of tubes; a partition in said as my nventoxn I have signedmy name in chamber to act as `a bae; an inclined purl Jresence of twoWtmesses,1s 16th day 0f }0 tion at the upper edge of saild larttion; anmember, 1910. air inlet aperture in the wal Q Sai-d Chmn 'Y ber; a latemaperture in the wal of the RENE MAROT latter for the dlscharge of themixture of 1 expanded sulfur dioxd and air.
